CHANGES IN RITOOLS VERSION 0.1-15
This is a maintenance release.
* Fixed an obscure bug in which we indirectly fiddled with `data.table` related
global options (#69)
* Disabled tests of RSVGTipsDevice-dependent functionality on Windows platforms,
where (as of this writing) RSVGTipsDevice does not build and check reliably and
is not distributed in binary through CRAN (#71)
CHANGES IN RITOOLS VERSION 0.1-14
This version was submitted to CRAN prematurely and ultimately was not released.
CHANGES IN RITOOLS VERSION 0.1-13
* With `xBalance`, you can now specify strata "foo" and "bar" by including
"+ strata(foo) + strata(bar)" in the `fmla` argument, without need to give
a separate `strata` argument (eg `strata=list(foo=~foo, bar=~bar)).
CHANGES IN RITOOLS VERSION 0.1-12
* Switched to base graphics instead of the lattice package for balance
plots.
* Option to make plots on absolute, instead of signed, values.
* Added the ability to include tooltips to balance plots when using
the RSVGTipsDevice package.
* Added a `balanceplot` function to handle plotting matrices, not just
`xbal` objects.
* Balance plots can be grouped into related variables. By default
factors are automatically grouped for `xbal` objects.
* Some performance improvements when certain results are not requested.
* `post.alignment.transform` argument to `xBalance` allows modifying
the data after per-stratum centering.
* `subset` method for `xbal` objects.
CHANGES in RItools v. 0.1-11
NEW FEATURES
* the null SD of the difference in adjusted means is now reportable as
"adj.means.diffs.sd"
* report="all" provides all relevant statistics
* Entering "args(xBalance)" is now useful as a reminder of report=
options.
DEPRECATED & DEFUNCT
* The default imputation method for missing data is the median. Before
0.1-9 it was the mean. To use the mean, use impfn=mean.default.
* Passing strata=NULL to xBalance is depracated, as it can be easy to
do inadvertently, with a misspelling of a non-null intended
argument. For no stratification, use list(unstrat=NULL), as is now
the default.
BUG FIXES
* display, align, etc arguments to xtable.xbal() have been enabled.
* In xBalance, when specifying a stratification using a formula with
several variables, as in "~x+y", the stratification you get is now
interaction(x,y) rather than just y.
